Dmitry Medvedev, the Russian president, said Moscow was bidding to help lead efforts to build a new world economic order after the old system collapsed in the global financial crisis.

Opening Russia’s annual economic forum in St Petersburg where hundreds of global chief executives have flocked, Mr Medvedev said the renewed interest in Russia this year was a sign of a changing world in which the institutions of the western-dominated world order had had their day amid thousands of corporate defaults and the threat of sovereign defaults.

“What had seemed untouchable has collapsed. The bubbles that created the illusion of flourishing economies have burst,” Mr Medvedev said. “For Russia this situation is a challenge and an opportunity. We are living in a unique time. And we should use it to build a modern, flourishing and strong Russia … which will be a co-founder of the new world economic order and a full participant in the collective political leadership of the post-crisis world.”
